运行“hedera-json-rpc-relay”时，如何配置与 Hedera 测试网的连接？

Question

我正在按照以下说明进行操作hedera-json-rpc-relay：具体来说docs/configuration.md，尝试运行连接到 Hedera Testnet 的 RPC 中继：

HEDERA_NETWORK=TESTNET
OPERATOR_ID_MAIN=0.0.3996280
OPERATOR_KEY_MAIN=<redacted>
OPERATOR_ID_ETH_SENDRAWTRANSACTION=
OPERATOR_KEY_ETH_SENDRAWTRANSACTION=
CHAIN_ID=0x128
MIRROR_NODE_URL=https://testnet.mirrornode.hedera.com/
E2E_RELAY_HOST=

请注意，OPERATOR_ID_MAIN和OPERATOR_KEY_MAIN已为门户获得，并已成功用于其他交易。

具体指令HEDERA_NETWORK是：

连接到哪个网络。自动填充主节点和镜像节点端点。可以是 MAINNET、PREVIEWNET、TESTNET 或网络 IP 映射 -> 节点 accountId，例如 {"127.0.0.1:50211":"0.0.3"}

但是，当我运行时npm run start，我收到以下错误Error: unknown network: TESTNET ...即使根据文档，这明确是允许的值。

（完整输出复制在下面<hr/>）。

启动 RPC 中继并将其连接到 Hedera 测试网的正确配置是什么？

Answer 1

这是必要的配置：

HEDERA_NETWORK=testnet
OPERATOR_ID_MAIN=0.0.3996280
OPERATOR_KEY_MAIN=<...redacted...>
CHAIN_ID=0x128
MIRROR_NODE_URL=https://testnet.mirrornode.hedera.com/

提交了一个补丁 以添加上述示例文件，以及 Hedera Mainnet 和 Hedera Previewnet 的等效文件。

此外，发生的错误是由于这一行：

HEDERA_NETWORK=TESTNET

它基本上失败了，因为它只接受所有小写字母。这也已 在同一补丁中修复，因此现在问题中的原始配置也将开始工作。
